Tambour

In classical architecture, a tambour (Fr.: "drum") is the inverted bell of the Corinthian capital around which are carved acanthus leaves for decoration.

The term also applies to the wall of a circular structure, whether on the ground or raised aloft on pendentives and carrying a dome, and to the drum shaped segments of a column, which is built up in several courses.
